SOCKET-FOR INCANDESCENT ELECTRIC LAMPS.

SPECIFICATION forming part of Letters Patent No. 748,338, dated December29, 1903.

Application filed June 18' 1903i Serial No. 162,122- (Il'o model To allwhom it may concern.-

Be it known that'I, CHARLES BAKELEY, a citizen of the United States,residing at Covingtou, in the county of Kenton and State ofKentucky,have invented certain new and useful Improvements in Socketsfor Incandescent Electric Lamps; and Ido declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in sockets for incandescentelectric lamps; and it consists in the peculiar construction andcombination of devices hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a vertical sectional view ofan incandescentelectric-lamp socket embodying my improvements. Fig. 2 isa similar view at right angles to Fig. 1. Fig. 3 is a vertical sectionalView of a modified form of my improved incandescent-electric-lampsocket. Fig. 4 is a similar view showing another modification.

In the embodiment of my invention I provide a base-piece 1, which ishere shown as cylindrical in form and is made of non-conductingmaterial. Through the said basepiece'extend openings 2, in which areinserted conducting-sleeves 3, which are retained in place therein byscrews4 5, disposed radially with reference thereto and which extendthrough openings in the base-piece. The line-wires a have their endsplaced in the said sleeves and secured therein by the binding orclamping screws 4. The base-piece is in practice secured in acylindrical casing 6 either by means of screws 7 or by other suitablemeans and after being thus secured is not thereafter disturbed.

The detachable portion 8 of the socket comprises a pair of circularheads 9 10, of insulating material, cylindrical tubular pieces 11, andsimilar pieces 12, interposed between them, bolts 13, which pass throughsaid pieces 11 and secure the said heads thereto, and conducting-bolts14 15, which respectively pass through the pieces 12 and said heads andconnect them together, the upper end of the said bolts being inserted inthe sleeves 2 and secured therein by the screws 5. Hence the saidportion 8 of the socket is detachably connected to the base-piece 1 andmay be removed therefrom without in any manner disturbing theconductingwires, which are attached to the said base-piece.

The conducting-bolt 15 is electrically connected to the flange at theinner end of the screw-collar 16, to which the lamp is connected in theusual manner and which forms one electrode. The heads of the screws 11also engage the said flange of the screw-collar, and in the saidscrew-collar is disposed a disk 17, of insulating material, which.covers the heads of the screws 11 and prevents them from casuallyworking loose and disconnecting the screw-collar. The other electrode isformed by a plate 18, which is secured on the inner side of the head 10by a conducting-screw 19, the head of which forms an electrode,centrally disposed in the screwcollar. Said screw 19 passes through thedisk 17 and is insulated thereby from the screw-collar. Said screw alsoserves to secure the said disk in place, as will be understood.

The plate 18 has a standard 20, provided with a bearing 21, at the outerend of which are cam-notches 22 and stop-notches 23, disposed at rightangles with reference to each 80 other. A cnt-out stem 24, which is anelectrical conductor, is journaled and movable longitudinally in thebearing 21, is provided at its outer end with a head or key 25, by whichit may be readily turned, and is further provided with atransversely-disposed stud 26, which coacts with the notches 22 to movethe said stem longitudinally in one direction when the stem is turnedand with the notches 23 to lock it against casual movement. The 0opposite end of the stem is thus adapted to engage and disengage aconductor 27, which is provided with a binding-screw 28. Aconducting-plate 29 is electrically connected to the bolt 14 by the nut30 and has an arm 31, 5 provided with a binding-screw 32. A fusewire 33has its ends secured to the conductor 27 and arm 31 of plate 29 by thebindingscrews 28 32, respectively.

By substituting a base-piece and socket- I00 casing of different size orshape the socket .will be converted into a receptacle or wallsocket. Itwill thus be adapted to all requirements where a socket or receptaclewith a cut-out key is required. The cut-out key 24 and plate 27 may beomitted and the plate 18 provided with an arm to carry the bindingscrew28 for the attachment of the fuse, thus converting the socket orreceptacle into a keyless socket or receptacle. Ihe non-conductingportion of the detachable part of the socket will preferably be in onepiece and will have hollow spaces for the screws to pass through.

By substituting a stud-bolt for the screw 19 and also substituting aWasher or ring for screw-shell 16 a lamp with Thomson-Houshaving anon-conducting base-piece, conducting-sleeves extending longitudinallytherethrough, and forming means for the reception and attachment of theends of the line-wires, conducting-bolts secured in said sleeves andprojecting from the base-section, and a detachable non-conductingsection, spaced from the base-section and secured on the saidconducting-bolts.

2. An incandescentelectric lamp socket havinga non-conductingbase-piece, conducting-sleeves extending longitudinally therethrough andforming means for the reception and attachment of the ends of theline-wires,

conducting-bolts secured in said sleeves and projecting from thebase-section, spacing tubular pieces on said conducting-bolts, and adetachable non-conducting section, spaced from the base-section by saidtubular pieces and secured on the said conducting-bolts.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

CHARLES BAKELEY.
